注解

通常，可以通过创建一个从派生的设置包装器类， ApplicationSettingsBase 并向此类添加特殊属性，将应用程序设置支持添加到应用程序。Typically, you can add application settings support to an application by creating a settings wrapper class, which is derived from ApplicationSettingsBase, and then add special properties to this class. 但是，此方法并不能充分封装控件的应用程序设置，因此无法从详细信息中屏蔽其容器。However, this approach does not sufficiently encapsulate application settings for a control so that its container is shielded from the details. IPersistComponentSettings接口为应用程序提供了一个标准接口，用于将应用程序设置状态更改请求与控件、组件或库模块通信。The IPersistComponentSettings interface provides an application with a standard interface for communicating application settings state change requests to a control, component, or library module. 设计时工具还依赖于此接口以正确管理控件和组件。Design-time tools also depend on this interface to properly manage controls and components.

属性
